To create a user first you would have the previlages then youo can create a user by using the below statement.
create user user_name identified by user_password

Once again your answer does not add anything to previous post.
Are you able to answer more than what was already said?

HI i think the proper and technical answer should be like this please correct me if i made any mistake


connect username/password ---any username whose have privs to create user

create user test identified by test ----user created

but still this account can't be use as no privs is assigned till now.

so give privs as;

grant connect,resource to test

above commands create user who can connect only further if we want to use account for other purpose we need to give more privs.

No, never use these predefined roles, above all NEVER use RESOURCE. You can use CONNECT in 10g and up, it is equivalent to CREATE SESSION privilege.
Always define yours with the appropriate privileges.

This is the reason why you MUST NOT give this role, you don't know what is inside.
Create your own role then you will know what privileges you give.

Create your own role then you will know what privileges you give.



Back then, not all but some DBAs created a user and granted CONNECT and RESOURCE roles to this newly created user by default. For most purposes, everyone was quite happy as these predefined roles were enough for an ordinary user to start working, while DBA didn't have to think about all possible privileges one could need.

Then it was suggested not to grant CONNECT and RESOURCE any more, but create your own roles (for example, MY_CONNECT and MY_RESOURCE), make sure which privileges I've granted to them and deal with these roles from now on.

However, what's wrong with the original CONNECT and RESOURCE? Why wouldn't I know which privileges they own? Something like this:
SQL> SELECT grantee, privilege, admin_option
  2  FROM DBA_SYS_PRIVS
  3  WHERE grantee IN ('CONNECT', 'RESOURCE')
  4  ORDER BY grantee, privilege;

GRANTEE                        PRIVILEGE                                ADM
------------------------------ ---------------------------------------- ---
CONNECT                        CREATE SESSION                           NO
RESOURCE                       CREATE CLUSTER                           NO
RESOURCE                       CREATE INDEXTYPE                         NO
RESOURCE                       CREATE OPERATOR                          NO
RESOURCE                       CREATE PROCEDURE                         NO
RESOURCE                       CREATE SEQUENCE                          NO
RESOURCE                       CREATE TABLE                             NO
RESOURCE                       CREATE TRIGGER                           NO
RESOURCE                       CREATE TYPE                              NO

9 rows selected.

SQL>

Now that I know what RESOURCE is, is it acceptable to grant it to my newly created user? Of course, if everyone's happy with these privileges? I guess it is.

However, not for long. Oracle announced that both CONNECT and RESOURCE roles will be deprecated in future Oracle versions.

Therefore, all these lovely privileges which once existed in Oracle 8i are about to be gone. For your information, these were
  • CONNECT:
    ALTER SESSION, CREATE CLUSTER, CREATE DATABASE LINK, CREATE SEQUENCE, CREATE SESSION, CREATE SYNONYM, CREATE TABLE, CREATE VIEW
  • RESOURCE:
    CREATE CLUSTER, CREATE INDEXTYPE, CREATE OPERATOR, CREATE PROCEDURE, CREATE SEQUENCE, CREATE TABLE, CREATE TRIGGER, CREATE TYPE
A conclusion? Do as Michel said - create your own role(s) and use them in the future.

In addition, well note that they are predefined role but the associated privileges list is Oracle proprietary and they can change it in any version as they want and they did it as LittleFoot showed it!
What happens now to your applications that rely on CONNECT?

Also note that with RESOURCE you hiddenly gain UNLIMITED TABLESPACE that is the privilege to full up your SYSTEM tablespace and crash your database. Useful this role? No, just dangerous.

Predefined roles are ONLY for Oracle, not for customers. Even DBA one.
